Food intake is mainly controlled in the hypothalamus via a series of functionally related nuclei, including the ventromedial nucleus of hypothalamus (VMN) and the lateral hypothalamic area (LHA). Since food intake is the product of meal number and meal size, we investigated the role of the VMN and LHA in ...

Growing interest in nutrition and health and the increase in the number of people eating away from home gives power and responsibility to retail foodservice operators. Employees of hotels, restaurants, and other food service establishments are in an important position to influence and impact the diet of the general public ...

Data collected from a sample of working individuals lunching at staff cafeterias were analysed to characterise contemporary food habits in terms of meal structure, eating outside meals, and other aspects of the organization of the daily food intake. Discrepancies were found between individuals' ideas of a proper meal and their ...

The effects of a single morning and evening carbohydrate-rich meal for 3 consecutive days on circadian phase of core body temperature (CBT), heart rate, and salivary melatonin rhythms were compared under controlled constant routine conditions. In 10 healthy young men entrained to a natural light-dark cycle with regular sleep timing, ...

Previous research suggests that enhancing the volume of a food preload without altering energy content can result in reduced appetite, although the limited evidence means that the conditions under which this effect will occur are not yet clear. In the present study, we used a Universal Eating Monitor (UEM) to ...

We hypothesized that food texture modifications might alter anticipatory reflexes, feeding behavior, and the postabsorptive consequences of ingestion. Two sets of complete meals with different textures but the same macronutrient composition were prepared. The first set was either a soup containing chunks of food (mixture) or the same soup blended ...

The objective of this study was to assess the effect of food and timing of meals on the bioavailability of didanosine from encapsulated enteric-coated beads. Four different independent, open-label, single-dose, randomized, crossover studies were conducted in healthy subjects (n = 20-30). Didanosine (400 mg) was given concomitantly with a high-fat ...

This book attempts to offer a new perspective on cancer as an evolutionary disease. It looks at several different cancers in detail - breast, colon and prostate to name but a few and reveals some fascinating facts about the illnesses and their history.

BACKGROUND: For persons unable to feed themselves, resistance to assistance with meals may result in increased morbidity and premature mortality because of inadequate nutritional intake. Additionally, unwillingness to accept food offered has social and ethical implications in all cultures and may influence caregiving. OBJECTIVE: As part of a larger study, ...

OBJECTIVE: The time of day of meal ingestion, the number of people present at the meal, the subjective state of hunger, and the estimated before-meal contents in the stomach have been established as influences on the amount eaten in a meal and these influences have been shown to be heritable. ...

Prior evidence has suggested that meal satiation in the marine mollusk Aplysia is associated with stretch of the crop. The current data, however, suggest that under some conditions, bulk in the crop can be dissociated from the propensity to feed. The crop was hyper-distended 6 h after a satiating meal ...

The study of postprandial metabolism is in the early stages compared with other areas of atherosclerosis research. Recent advances in postprandial research have included improvements in methodology and the investigation of factors that modulate the lipemic response to a meal. Enough studies have now been performed that normal ranges have ...

A consumer survey was conducted in a university fastfood mall to determine the food consumption and buying patterns of Philippine university students. The survey established that a typical fastfood consumer in the test university foodmall is female between 16 and 22 years old, with a purchasing capability of < or ...

Experiments were conducted in a laboratory autoclave and in a commercial rendering plant to set a limit for the R-value of an enzyme-linked immunosorbent assay (ELISA) to prove that animal meal had been sufficiently heat-treated. The immunoassay method is currently the only technique used to check for appropriate sterilization of ...

Intraganglionic laminar endings (IGLEs) and intramuscular arrays (IMAs) are the two putative mechanoreceptors that the vagus nerve supplies to gastrointestinal smooth muscle. To examine whether neurotrophin-4 (NT-4)-deficient mice, which have only 45% of the normal number of nodose ganglion neurons, exhibit selective losses of these endings and potentially provide a ...

BACKGROUND: It has been suggested that hunger may be delayed and food intake reduced under metabolic conditions that spare carbohydrate oxidation. OBJECTIVE: Our objective was to examine the role of glucose metabolism in the control of food intake in men by using medium-chain triacylglycerols (MCTs) to spare carbohydrate oxidation. DESIGN: ...

Feeding behaviour in the weaning period is important theoretically and practically. The aim of the study was to develop appropriate observational codes for its description, to assess their reliability, and to examine the relationships between feeding behaviour, meal duration, and food intake. One hundred children aged 12-14 months were visited ...

OBJECTIVES: The time of day of meal ingestion, the number of people present at the meal, the subjective state of hunger, and the estimated before-meal contents in the stomach have been established as influences on the amount eaten in a meal, and this influence has been shown to be heritable. ...

BACKGROUND: Fasting is required by the Jewish and Islamic religions, and may sometimes be necessary for non-religious reasons as well. Very little empiric data are available on the effect of 24 hours of food and water deprivation. OBJECTIVES: To compare the effects of the dietary composition of different pre-fast meals ...

AIMS: To determine the effects of acute hyperglycaemia on appetite and food intake in Type 1 diabetes mellitus. METHODS: Two separate studies, each involving eight adults with uncomplicated Type 1 diabetes, were performed: one in the fasted state (A) and the other after a nutrient preload (B). In both studies, ...

Spaghetti was prepared by replacing either 5 or 10% semolina or farina with corn gluten meal, a high-protein fraction from the wet milling of corn, to increase the protein content of pasta. Spaghetti fortified with corn gluten meal had a similar cooked weight and cooking loss but was less firm ...

BACKGROUND: Cognitive restraint, a stable disposition to limit food intake, can be assessed by questionnaires, but there is no quantitative, objective measure of its effect. OBJECTIVE: The goal was to provide an objective measure of the intake-limiting effects of cognitive restraint by testing meal intake under conditions intended to minimize ...

AIM: To study the ecological variation of intake of cassava foods and dietary cyanide load. DESIGN: Ecological study design. SETTING: Five communities in south-western Nigeria where tropical ataxic neuropathy (TAN) was described as endemic (area A), 11 communities in south-western Nigeria where TAN was described as absent (area B), and ...

The heritability of the before and after meal self-ratings of palatability and their relationship to food intake was investigated with 86 identical and 78 fraternal same-sex and 51 fraternal mixed gender adult twin pairs who were paid to maintain 7-day food intake diaries. From the diary reports, the total and ...

We investigated the effect of a meal feeding schedule (MFS) on food intake, hepatic glycogen synthesis, hepatic capacity to produce glucose and glycemia in rats. The MFS comprised free access to food for a 2-hour period daily at a fixed mealtime (8.00-10.00 a.m.) for 13 days. The control group was ...

The study objective was to quantify interpretations of the term "balanced meals" used in food security status assessments. Telephone interviews included 77 charitable food recipients in Hawaiì. After participants first responded to the question of whether they could afford to eat balanced meals, they next defined what a "balanced meal" ...

To test if a diet of 4.2 MJ/24 h as six isocaloric meals would result in a lower subsequent energy intake, or greater energy output than (a) 4.2 MJ/24 h as two isocaloric meals or (b) a morning fast followed by free access to food. Subjects were confined to the ...

The milk protein, caseinomacropeptide (CMP), is a predominant breakdown product of casein in the human stomach, and may aid in the regulation of food intake. Using a human feeding study design, this project assessed the effects of CMP on satiety and satiation by measuring the amount of food consumed at ...

OBJECTIVE: A consideration of eating patterns in the general population is necessary when deriving food-based dietary guidelines (FBDG) as promoting the intake of one food may indirectly result in the increased consumption of another, which may not always be desirable. A number of issues that influence meal patterns such as ...

BACKGROUND: Taste and smell losses occur with aging. These changes may decrease the enjoyment of food and may subsequently reduce food consumption and negatively influence the nutritional status of elderly persons, especially those who are frail. The objective of this study was to determine if the addition of flavor enhancers ...

Varying the time since the last meal is one means of manipulating feeding motivation. In order to use this method effectively it is necessary to know whether and the extent to which effects of one pre-meal interval are carried over to affect the behaviour during the following meals. Pre-meal interval ...

In humans, eating is assumed to be regulated within a neuronal circuitry integrating hypothalamic "feeding centers" with neocortical regions. Here, DC potentials were recorded in food deprived men to demonstrate a graded tuning of neocortical excitability in conjunction with meal ingestion. In the beginning of food ingestion a pronounced negative ...

The present authors examined the effectiveness of a behavioural intervention which included escape extinction and differential reinforcement of each bite eaten to treat non-organic food refusal in a child with Williams syndrome. The intervention was implemented by the child's mother in the home during normal meal schedules. The child was ...

Consumer researchers consider convenience orientation towards meal preparation to be a relevant construct for understanding consumer behavior towards foods. This study set out to conceptualize this construct and to develop a scale that measures it. As examined in two different samples of meal preparers, the resulting scale is reliable, satisfies ...

The noncompetitive NMDA receptor antagonist MK801 has been reported to increase food intake in rats during scheduled test meals of palatable foods or after food deprivation, but not in nondeprived rats given rodent chow. To determine if MK801 has an effect on spontaneous meals, MK801 (100 microg/kg) was administered 15 ...

The contribution of taste to the food choices of foraging rats was examined. Rats in a laboratory foraging paradigm searched for sequential opportunities to eat at two feeders containing chow-based food pellets that were plain or flavored with saccharin or citric acid. Pellets cost the same number of bar presses ...

The variability of anticipating a meal was investigated. Sprague-Dawley rats earned food by inspecting a food source during a 3-hr interval. Food was not available at other times. In Experiment 1, the meal started 3 or 7 hr after light offset in a 12-hr light-dark cycle. Experiment 2 was conducted ...

We investigated the effects of food palatability on the thermic effect of feeding (TEF), substrate oxidation and circulating glucose and insulin. Healthy young men (23.4+/-1.0, SD, years, n=10) and older men (69.4+/-1.3, years, n=9) were resident in a metabolic unit for two 2-day study periods. On the second day of ...

Rats trained to eat a single daily meal (MF rats), from 8:00-10:00 a.m., increased food intake from the 1st to the 12th (125%) day of feeding training. In this work we compared the influence of the higher food ingestion in the last meal and feeding training on hepatic gluconeogenesis. Thus, ...

In two independent demonstrations, pre-prepared food was served in different environments: first, identical prepared meals were served in both a training restaurant and in a student cafeteria; second, a prepared main dish was served in a food science laboratory class, and as part of an entire meal in two student ...

Methodology was developed and evaluated for the rapid detection of castor bean meal (CBM) containing the toxic protein ricin by using Fourier transform near-infrared (FT-NIR) spectroscopy and multivariate techniques. The method is intended to be a prototype to develop a more general approach to detect food tampering. Measurements were made ...

Because daily food intake is the product of the size of a meal and the frequency of meals ingested, the characteristic of meal size to meal number during a 24-h light-dark cycle constitutes an identifiable pattern specific to normal states and obesity and that occurs during early cancer anorexia. An ...

The experimental analysis of the controls of eating has undergone a paradigmatic shift in the past decade. Instead of seeing meals as a problem of how intake serves metabolism and nutritional homeostasis, meals are now seen as a problem in behavioral neuroscience. The major developments underlying this significant change are ...

This study investigated the influence of sensory stimulation, with and without post-ingestive consequences, on satiation by varying the form of a preload and the timing of a mixed meal presented after the preload. Twenty-four, normal-weight, non-dieting, college-aged women were randomized to different preload groups: water preload (Water), sip-and-spit energy-dense preload ...
